As a member of the G Master line, it is designed for outstanding resolution and sharpness with minimal aberrations, something assisted by the implementation of one Super ED and two ED elements as well as a Nano AR coating. It also features a relatively compact size through the use of an f/4.5-5.6 maximum aperture range, and it is equipped with both a Direct Drive SSM autofocus system as Optical SteadyShot image stabilization for outstanding performance at all focal lengths.

The lens features numerous other settings and controls for making operation smooth and intuitive for a variety of shooting styles. This includes a zoom torque adjustment ring that lets users dial in the stiffness of the zoom mechanism. It also has an internal focus system with a minimum focus distance of just 3.22' as well as focus range limiter switch for faster focusing. Other physical controls and options include multiple customizable focus hold buttons, an AF/MF switch, and a removable and rotatable tripod mount.

A maximum aperture range of f/4.5-5.6 helps minimize size and weight while providing excellent performance in a variety of applications.

Two extra-low dispersion elements and one Super ED element are featured in the lens design and help to control chromatic aberrations and reduce color fringing for increased clarity and color fidelity.

A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.

The front lens element features a fluorine coating to protect against smudges and dust from adhering to the glass surface.

Optical SteadyShot image stabilization helps to minimize the appearance of camera shake for sharper imagery when shooting handheld with slower shutter speeds. This stabilization system can also be combined with select camera's sensor-shift type image stabilization for more effective control of camera blur.

A Direct Drive SSM system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control.

Dust and weather-sealed construction benefits using the lens in inclement shooting conditions.
